Expert Tips (Before You Start!)

  1. Peanut Butter Matters: Use natural, unsweetened peanut butter to keep carbs low and the texture perfect. Avoid peanut butter with added oils or sugars.
  2. Sweetener Texture: Powdered sweeteners blend better than granulated ones and prevent gritty cookies.
  3. Visual Cues: These cookies will look soft when they come out of the oven but firm up as they cool—don’t overbake!

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
  2. Mix Ingredients: In a large mixing bowl, combine the peanut butter, powdered sweetener, egg, almond flour, and vanilla extract (if using). Stir until the dough is thick and well mixed.
  3. Shape Cookies: Scoop out a tablespoon of dough and roll it into a ball. Place it on the prepared baking sheet, leaving about 2 inches of space between cookies.
  4. Create Crisscross Pattern: Using a fork, press down on each dough ball to flatten it slightly and create the classic crisscross pattern.
  5. Bake: Bake for 12 minutes, or until the edges are set but the centers are still soft.
  6. Cool: Remove the baking sheet from the oven and let the cookies cool for 10 minutes before transferring them to a wire rack to cool completely.

Pro Tip: Store in an airtight container at room temperature for up to 5 days or freeze for longer storage.
